Classic DDA Raycasting: Renders a 2D grid map into a pseudo-3D environment using the Digital Differential Analyzer algorithm.
Textured Walls & Distance Shading: Procedurally generated wall textures mapped to walls, with Y-axis shading and distance-based darkening for depth.
Z-Buffered Sprites: Enemy sprites are correctly projected into the 3D world and occluded by walls using a 1D Z-Buffer.
Near-Clip Fix: Prevents extreme stuttering, screen-filling, and division-by-zero errors when the player gets too close to an enemy.
Hit-Scan Combat: Shoot enemies using dynamic screen-space crosshair detection.
View Modes: Toggle between a First-Person Shooter (FPS) view and an Over-The-Shoulder (OTS) cybernetic avatar view.
Procedural Assets: No external images needed! Wall textures, enemy sprites, and weapon models are generated purely via Skia canvas primitives.
Threaded Game Loop: Physics and input are processed in a background thread, while rendering is safely synchronized to the main UI thread for a smooth framerate.
